Entrepreneur, Business Leader, Investor, and Strategic Advisor. MIT PhD alum.

Plastik Ai is harnessing the power of artificial intelligence to revolutionize the plastic and plastic compounding industries, bridging the gap between engineers using plastics and manufacturers creating them. At the core of our platform is Herman, an advanced tool-using AI agent designed to match product requirements with ideal plastic compounds. Herman leverages a combination of public and proprietary data to enable rapid and precise material recommendations, which can be easily ordered within a marketplace.

We are looking for a skilled AI/ML Engineer to play a key role in building the AI agents, and agentic tools that fine tune and optimize open source LLM models to add value to design engineers and manufacturing companies. Our product is a innovative two-sided marketplace augmented by AI tools enabling easy plastic selection, sourcing, and logistics. This transformative approach unlocks new possibilities in sustainable plastics innovation, enabling faster, smarter, and more efficient product development and material discovery.

As part of our cross-disciplinary team, you will work alongside MIT-trained engineers, scientists, and business professionals to build a groundbreaking AI platform for the plastics industry. Join us in transforming how the world approaches plastic materials through cutting-edge technology and innovation.
